Another angle is that it's a fan-made initiative. Maybe fans are creating content (like a virtual concert) called Joelina Falk VK inspired by Nine Days. I can mention the fan community's role in keeping the band's legacy alive.
Including a call to action for readers to verify with the artists or official channels would be prudent. Also, offering to help with more information if the user can provide clarification on the names would be good.
Alternatively, the user might be referring to something fictional, like a story or a song. Without more context, it's hard to tell. Since I can't search the internet, I'll have to proceed with assumptions based on existing knowledge.
So the structure could be: introduction to Nine Days, possible connections to Joelina Falk and VK, the role of VK in promoting music, and a conclusion encouraging further exploration.
